The Eye and the Camera have a lot in common. • They both have compound lenses - which are converging lens refracting the light to a focal point on the light-sensitive layer to record an image.
To focus a camera you move the lens backward or forward.
The eye is focused by the ciliary muscle, which stretches the lens,changing its shape.
• To control how much light gets in.
The iris in your eye changes the size of the pupil - the dark spot in thecenter of your eye, which controls the amount of light that enters.
Cameras adjust to let different amounts of light in by using the aperture andthe shutter controls how long the light is allowed to get through.
• The retina is like the film in a camera, covering the back of the eye
